How does Sleighbells compare with other water systems in Washington County?
By EPA's size categories, Sleighbells is a very small system (500 people or fewer). Washington County has 97 active public water systems. Its population served is well below the county average of 6,158 people per system, and accounts for less than 0.1% of the 597,296 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Sleighbells is well below that figure.
What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Oregon has 1,250 active transient non-community water systems, 49% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.
Who owns and regulates Sleighbells?
EPA lists Sleighbells as privately owned. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 65 of the 97 active systems in Washington County (67%) are also privately owned.
Does Sleighbells have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2025. The violations listed here began between May 2020 and December 2025. By type: 11 monitoring and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (11 of them). EPA lists 10 as resolved and 2 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
